School server
The XO school Server, or XS, is one of the products of the OLPC project, designed to complement the XO laptop. It is a Linux-based system engineered to be installed on generic low-end servers. We outline hardware recommendations and in the future, we may offer a hardware platform specially designed for the role.
When we deploy one laptop per child, we must also provide additional infrastructure extending the capabilities of the laptops. While the laptops are self-sufficient for many learning activities, other activities and services depend on the School Server providing connectivity, shared resources and services. Services, tools and activities running on the School Server allow asynchronous interaction, can use larger storage capacity, and take advantage of the processing power of the XS.
Community Edition
- XS Community Edition is a modular and teacher-friendly project, allowing XO laptops to be used as servers, modernized with Fedora 18+ and CentOS, but is not yet supported or promoted by OLPC,
- XS Community Blog, begun March 2012 by George Hunt.
